Dan DeLuca's picks: Dom Flemons, 'Red Army,' and Ariana Grande

Dom Flemons. The self-proclaimed "American songster" is a folk-singing musical anthropologist and Pete Seeger enthusiast who cofounded the still-together string band Carolina Chocolate Drops after meeting Rhiannon Giddens and Justin Giddens at the Black Banjo Gathering in North Carolina in 2005. Tuesday at the Sellersville Theater.

Simian Mobile Disco. High-energy English electronic duo of James Ford and Jas Shaw play an intimate DJ set on South Broad, with JDH and Dave P. Wednesday at the Dolphin Tavern.

"Red Army." Gabe Potsky's documentary about the Soviet national ice hockey team is a crafty and compelling history lesson about elite athletes as pawns in a Cold War geopolitical chess match. The movie smartly focuses on Red Army (and later Detroit Red Wings and Montreal Canadians) defenseman Slava Fetisov, but unfortunately it doesn't include the 4-1 thumping of the Soviet squad by the 1976 Flyers. Playing at the Ritz 5.

Ryan Bingham. The sandpaper-voiced Texas outlaw whose songs were featured in the 2009 Jeff Bridges movie Crazy Heart has himself the best title for a country music album likely to come out in 2015, with the rock-solid new Fear and Saturday Night. Thursday, with Lucero and Twin Forks, at the World Café at the Queen, in Wilmington.

Ariana Grande. She's the mini-Mariah, the big-voice-in-a-small-package pop pixie who had two of the biggest hits of 2014 with her Iggy Azalea collabo "Problem" and the onomatopoeic Jessie J.- Nicki Minaj team-up "Bang Bang." She's most recently been heard from as a guest vocalist on the more adventurous "Adore," by Norwegian producer Cashmere Cat. Thursday at the Wells Fargo Center, with Rixton.
